Inventory shortfalls suggest iMac refresh around the corner

Low iMac inventory numbers may suggest an upcoming refresh. If these screenshots from an Apple Authorized Service Provider who asked not to be identified are a true reflection of channel supply on current inventory, numbers are running low -- way low.

Our AASP friend writes, "While putting in an order today we stumbled upon both our suppliers have no stock of 21- or 27-inch iMacs. One picture has an estimated ETA while the other shows all current models at zero stock. All four models look similar to the picture that displays the ETAs."
